amdgpu_devi...s_dc_support(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, this is amdgpu_device_asic_has_dc_support — the little function that tells you whether DC actually supports the asic. that's it. that's the whole job. it's from the Kernel API Manual (the amdgpu_devi...s_dc_support(9) page, yes that truncation is really how it's printed, don't come for me) 🎀

✨ SYNOPSIS ✨

bool amdgpu_device_asic_has_dc_support (struct pci_dev *pdev , enum
       amd_asic_type asic_type );

it returns a bool, it takes two things, and we're gonna go through both rn 🫶

🌸 ARGUMENTS 🌸

  • pdev — the pci device context. yeah. the actual device we're talking about 💖
  • asic_type — the AMD asic type. that's the enum, that's the flavor of silicon 🔥

🦋 DESCRIPTION 🦋

so what does it do. it checks if there's DC support for an asic — and by DC we mean the new modesetting infrastructre (yes that's spelled like that in the original, i'm not fixing it, i'm just the messenger 😭).

returns true if DC has support, false if not. no in-between, no vibes, just a boolean. periodt. ✨

lowkey the whole function is one vibe check on a single asic. it either passes or it doesn't. 💅

👑 SEE ALSO 👑

okay this is the long part, and i mean long. every single one of these is a real cross-reference, don't skip, i'm watching 👀
